What is M&A tax due diligence?

M&A tax due diligence identifies and quantifies tax risks and opportunities before an acquisition, disposition, merger, or restructuring closes. BD Emerson reviews federal, state, local, and international tax matters and connects the findings to transaction structure, purchase price, agreement protections, and post-close integration. The work helps buyers and sellers make informed choices while structure, price, and risk allocation can still change.

  • Corporate income tax returns and provisions
  • Federal, state, and local tax exposures
  • Sales and use tax, income and franchise tax, and economic nexus
  • Employment tax and compensation matters
  • Tax attributes, NOLs, credits, and limitations
  • Transfer pricing and international tax
  • Entity structure and ownership changes
  • Tax accounting and GAAP/SEC reporting
  • Transaction costs and deductibility
  • Purchase price allocation and asset basis
  • Tax provisions in the purchase agreement
Our approach

How can tax diligence affect the deal?

01

Quantify exposures

We identify potential liabilities, estimate exposure ranges where supportable, and distinguish known positions from areas requiring further analysis. This helps the deal team understand materiality and prioritize action.

02

Evaluate structure

We analyze asset-versus-stock alternatives, entity structure, tax elections, reorganizations, and other approaches. Section 338(h)(10) elections, F reorganizations, and related planning may be relevant depending on the entities, parties, and tax objectives.

03

Protect the agreement

Findings may inform indemnities, escrows, representations, covenants, purchase-price adjustments, closing conditions, and other protections. The output is formatted for deal teams and boards rather than as an isolated technical memorandum.

04

Plan for post-close

Tax diligence can identify short-period returns, attribute carryovers, combined-group reporting, systems changes, filing obligations, and integration requirements. Addressing these items before closing reduces avoidable disruption.

Our Advantage

Why BD Emerson for M&A tax

Visible while it still matters

Risks are surfaced while structure, price, and protections can still change, not after the buyer has lost the ability to negotiate.

Formatted for the deal team

Findings are presented as issue, periods, entities, exposure, evidence, and options for negotiation, not as an isolated technical memo.

Connected to the whole deal

Tax work is coordinated with financial diligence, valuation, commercial review, and integration, so a tax attribute, a state exposure, or a PPA implication is understood in the context of the business.

We had a hard time finding the right company to partner with in support of our compliance journey. Some vendors sell the idea that they do the work, but then you end up doing everything. The ambiguity is what killed our last project. BD Emerson’s team has such great technical knowledge and understands the standard so well that they made us comfortable with moving fast. This has led to us closing major enterprise customers that were previously out of reach because of security and compliance.

Lead an enterprise initiative to overhaul the organization's technology stack from ecommerce, corporate tech, and corporate security.

Supported ISO 42001 exercise and served as internal auditor.

Rubrik's privacy and compliance team began with the backbone of BD Emerson. BD Emerson supported building out the privacy program, GRC (ISO 27001, SOC 2, CMMC, FedRAMP), and the appsec function.

We needed a partner who could move quickly, without sacrificing precision. BD Emerson brought the expertise, structure, and speed we were looking for. Their team became an extension of ours, embedding themselves across the organization, guiding us step by step, and giving us confidence in areas we hadn’t tackled before. The internal audit they conducted was so detailed that even the external auditors called it out. Achieving ISO 27001 with zero nonconformities says everything you need to know about the quality of the partnership.
